Improvement in the manufacture of flocked water-proof fabrics



UNITED STATES PATENT ()FFICE.

EDWIN L. SIMPSON, OF MONROE, ASSIGNOR TO HIMSELF AND JARED WILSON POST,-OF NEW HAVEN, CONNECTICUT.

IMPROVEMENT IN THE MANUFACTURE OF FLOCKED WATER-PROOF FABRICS.

Specification forming part of Letters Patent N0. 38.006, dated March 24, 18%.

To all whom it may concern.-

Be it known that I, EDWIN L. SIMPSON, of Monroe, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvementin Water-Proof Fabrics; and I do hereby declare the following to be a full, clear, and exact description thereof.

The nature of my invention consists in applying to fabrics my water-proof compound, for which I have applied for Letters Patent in even date herewith, and adding thereto a coating of flocks, thus producing a fabric having the appearance of other known water-proof flocked fabrics, and equally impervious to air or water, but without the offensive odor always attending the latter, occasioned by the use of sulphur or the process known as vulcanizing.

To enable others skilled in the art to make myimproved fabrics, I will proceed to describe my method of so doing.

I first spread upon the fabrics to be flocked one or more coats (as the nature of the material may require; the thinner the material such as silk-two coats 'are suflicient; for thicker goods, as heavy cottons, canton-flannels, &c., three or more coats are better) of my water-proof compound, for which I have applied for Letters Patent, as before stated, and fully described in the specification accompanying said application. After these coats have become dry, I then add one coat of the oil compound or varnish described and claimed in the application and specification before referred to; and immediately after the varnish is spread, and while it is in an adhesive state, I apply the flocks, or similar material, by sifting them in excess upon the varnished surface, and applying pressure by rolling or otherwise, and afterward removing the excess or so much as does not adhere to the surface. I do this by means of a revolving brush; but other methodsmayanswerthesamepurpose. When this is done I hang the fabric in a room heated to abont160 Fahrenheit for twenty-four hours, or longer, if necessary. I then expose them to the sun and air for one day, more or less. The odor arising from the cam phene is entirely removed, and my fabrics are complete and as free from odor as before the compound or flocks were applied.

It is not necessary that the flocks be applied immediately after varnishing, as the fabric may be allowed to dry after varnishing. Then by applying camphene or naphtha to the varnished surface it will quickly become soft and adhesive, when the flocks are to be applied, as before; but the first I find to be more convenient, but no better.

I am aware that water-proof flocked fabrics have been mannfacturedas in the patent of J. T. Trotter, January 3, 1860. Therefore I do not claim producing flocked fabrics; but

WhatI claim as new and useful, and desire to secure by Letters Patent, is-

Coating water-proof fabrics in the manner herein described with flocks or similar material when the said fabrics are prepared in the manner substantially as herein set forth.
